Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A method for processing a measurement gap, comprising: receiving a radio resource control (RRC) assignment on a downlink for a measurement gap for tuning from a source carrier frequency to a target carrier frequency; determining a scheduling conflict arising from a beginning portion of a transmission time interval (TTI) bundle colliding with the measurement gap, an end portion of a TTI bundle colliding with the measurement gap, or an entire TTI bundle colliding with the measurement gap; and performing a medium access control (MAC) process in accordance with a protocol predefined for the scheduling conflict by transmitting a portion of the TTI bundle that does not overlap with the measurement gap and canceling the colliding portion.
A method for handling measurement gaps in wireless communication. The user equipment (UE) receives an instruction from the network (RRC assignment) indicating that a measurement gap will occur to tune from the current carrier frequency to another. The UE detects if this measurement gap causes a conflict with a transmission time interval (TTI) bundle, where either the beginning, end, or entire TTI bundle collides with the gap. If a conflict exists, the UE transmits only the portion of the TTI bundle that *doesn't* overlap with the measurement gap. The colliding portion is dropped, following a pre-defined protocol.
2. The method of claim 1 , wherein: the scheduling conflict arises from an end of the TTI bundle colliding with the measurement gap; the portion of the TTI bundle that does not overlap with the measurement gap is a beginning portion of the TTI bundle; the colliding portion of the TTI bundle that overlaps with the measurement gap is a colliding end portion of the TTI bundle; and the MAC process further comprises: using ACK/NAK feedback for a last intended TTI of the bundle, if an ACK/NAK is received, and considering this bundle acknowledged if an ACK/NAK for the last intended TTI of the TTI bundle is not received and collides with the measurement gap.
The method of handling measurement gaps where the *end* of a TTI bundle collides with the gap. Only the *beginning* portion of the TTI bundle is transmitted. The colliding end portion is dropped. The protocol also considers the ACK/NAK feedback for the last intended TTI within the bundle. If an ACK/NAK *is* received, the bundle is considered acknowledged. However, if an ACK/NAK is *not* received because it collides with the measurement gap, the bundle is also considered acknowledged. Effectively, the absence of a negative acknowledgement due to collision is treated as a positive acknowledgement.
3. The method of claim 1 , wherein: the scheduling conflict arises from a beginning of the TTI bundle colliding with the measurement gap; the portion of the TTI bundle that does not overlap with the measurement gap is an ending portion of the TTI bundle; the colliding portion of the TTI bundle that overlaps with the measurement gap is a colliding beginning portion of the TTI bundle; and the MAC process further comprises behaving in accordance with ACK/NAK feedback received for a last intended TTI of the bundle.
The method of handling measurement gaps where the *beginning* of a TTI bundle collides with the measurement gap. Only the *ending* portion of the TTI bundle is transmitted. The colliding beginning portion of the TTI bundle is dropped. The ACK/NAK feedback for the *last* intended TTI of the bundle determines the success or failure of the bundle transmission, in accordance with standard MAC protocol behavior.
4. The method of claim 1 , wherein: the scheduling conflict arises from the entire TTI bundle colliding with the measurement gap; the colliding portion of the TTI bundle that overlaps with the measurement gap is the entire TTI bundle; and the MAC process further comprises considering not acknowledged for the TTI bundle.
The method of handling measurement gaps where the *entire* TTI bundle collides with the measurement gap. The entire TTI bundle is dropped (not transmitted). The TTI bundle is then considered "not acknowledged." Therefore, the UE will assume that the data was not successfully received and handle accordingly (e.g. retransmit).
5.
